1. A two component high strength infiltrant system comprising:
- a resin component comprising;
about 70 to about 90% by weight of resin component of an epoxy resin; and
about 10 to about 30% by weight of resin component of a diluent; and
a hardener component comprising;
an amine selected from unmodified aliphatic amines, modified aliphatic amines, unmodified cycloaliphatic amines, modified cycloaliphatic amines, or combinations thereof;
an amide selected from modified amidoamines, unmodified amidoamines, or combinations thereof; and
optionally a catalyst;
wherein the infiltrant system has a mixed viscosity of less than 150 cps.

Abstract
An infiltrant system for rapid prototyping processes. The infiltrant system generally includes a resin component and a hardener component. The resin component typically includes an epoxy resin, and a diluent. The hardener component typically includes an amine, optionally an amide, and optionally a catalyst. High strength infiltrant systems, flexible infiltrant systems, and a method for infiltrating a part are also described.
